CG Presents: Minecraft Redstone Pistons

Hello youtube and welcome to another episode of cg presents in this episode we will be covering pistons fun and first let’s go move out move now whatever oh my gosh this is utterly ridiculous um ignoring that cow on the rave let’s do this video back on topic um

Okay covering what we went over the past few episodes inputs such as switches buttons pressure plates things like that transferring redstone power including extending it stuff like that we covered outputs such as doors droppers dispensers we covered weakly powered blocks strongly powered blocks normal things that aren’t really all that special

Which is a different concept than the signal strength of redstone then in the second episode we covered gates which apparently are not the kind that keep cows in but they’re still they still do some neat stuff with redstone and we covered a diode let me see how am i doing on time okay

Well we better move on to the pistons now which is the point of this episode if we’re going to finish this in 10 minutes pistons what do they do they push blocks they can push all the way up to one two three four five six seven eight nine ten eleven twelve blocks

If you try to add a thirteenth it does not work pistons will also push um entity or mobs i think is what everyone’s calling them that is unless they there is something blocking it and then it just you go into the piston or whatever block is pushing

Which can cause suffocation damage so be careful with that so how do you power a piston well like any sort of output that we have already went over you can power a block next to it or you can do it to where you’re going directly into the piston like here

So a piston can be powered by this block or this block or that block or the block behind it is an exception to that rule it does not follow all the same rules as everything else it cannot be powered by the block that it is facing into so if i take this here

I’ll run this red zone around that way it does nothing even if we make this strongly powered no nothing it just extended there because now we’re firing this block which is next to it well there is an exception to that exception ignore that though because exceptions to exceptions are really hard to understand

I have a simpler way of going over it a piston can be powered by the blocks around it unless it’s a block it’s being it’s facing into so you remember that and then you think okay in any case at all does it no matter what direction it’s facing it can

Be powered by this block or that block okay so put a block there let’s go like that and bam there it is strangely enough if it’s air it still works now i think that has something to do with uh i have a theory another one of my theories okay

Now the pistons taken up two blocks now one now two well if we treat that as like part of an output thing like the door it’s kind of big then we can power any of these blocks here and keep it going darn well let’s try that let’s take a switch and put it

There and turn this one off and there it works so that’s kind of the reason for that it’s taking up two blocks you’re pretty much directly powering this it’s kind of strange going up because it seems to that seems to kind of stick going by its behavior strange

You can also power the block to above it see this block can power that piston so i turn it on and lo and behold it does not work but i promise y’all that block is powering that piston well let’s prod it a bit there we go now it’s working

So why does that work well i mentioned the whole rule about it taking up two blocks it can be powered by any of those well whenever you power the let me turn this off okay power the redstone this block is now weekly power what we call weakly powered

Well whenever it changes that state it notifies the blocks around it that something is changed okay well the piston isn’t beside it so the piston never gets told that it’s supposed that this block is powered now and so the piston is supposed to be extended but doesn’t know it

So what we do is we put a block next to it or update one of the blocks already next to it and that update will notify the piston that something around it has changed even though it’s referring to like if we place that there it’s referring to this

Block but the piston will wake up it will look around and be like oh hey i’m supposed to be extended and then it just jumps right back up to there so if that’s the case how come turning it off makes it retract well now the pistons beside the block so

It’s going to be notified of it if we were to take the piston and turn it that way and then turn it off it’s not next to it so it doesn’t know it’s supposed to do that okay now let’s jump right over to sticky pistons they work exactly the same way

As pistons they follow all the same rules they both push blocks the only difference is that sticky pistons will pull the block back down or back to them whenever they retract like the normal ones a sticky piston can push 12 blocks i’m just gonna put four here

But it only pulls back the one block that it is attached to and the stickiness only has the stickiness only has an effect when it is being pulled or when it is being pushed so i go like that it isn’t grabbing this block it looks

Like it but it’s not it’s just next to it now i turn it off and it’s going to grab the block pull it back and then it’s going to let go and the sand is going to fall so the stickiness only applies when the block is moving okay hey

Well thank y’all for watching that’s about it for the pistons i think we covered everything and we pretty much understand this now we know that the blocks up here are next to the pistons and so keeping them powered uh knocking that down breaking that circuit so this is a not gate we know

From episode two diode doesn’t really matter upwards transmission another not gate ignites tnt it probably looks a little bit simple a lot simpler now and it looks like we have hit the tail end of this video um pistons can be used for all sorts of stuff just use your imagination doors

Draw bridges hidden areas bed switches are really cool if you want to look into those those use the two block above it trick i hope y’all tune in next time we’re past the basics but we’re just grazing the surface of redstone in the next redstone video we’ll be going into clocks

And not consider that about intermediate in the meantime 100 points for the first person to accurately count the number of pens y’all heard in this video that’s uh give me right there five points for each for each additional pen in the comments don’t worry because cow pens are not at

All rare so you’ll find a lot of them the competition ends when the next video comes out and i’ll see y’all then
